All stocked ranges

Our stocked O-rings include metric sizes and inch sizes to a range of international, national and industry standards.

These are held in a variety of general and high performance elastomers to suit the vast majority of industrial and specialised oil and gas sector applications.

If we do not hold the exact sizes you require, we have the flexible production schedules, within our 'lean' manufacturing system, to mould them on very short lead times to meet your most urgent needs.
